"Using those Guardians for spirit fusion?"

"Yes, thank you, senior, for your help." Jiang Miaoyin replied sweetly, as the Curse Spirit stepped forward to push. The Bronze Giant Gate immediately emitted an even louder noise, opening a crack in the middle, from which an extremely cold chill poured out.

Chu Xiu was somewhat surprised; the Curse Spirit’s power was terrifyingly great, with a Constitution probably nearing twenty thousand.

"This girl is not to be underestimated either."

Without thinking further, Chu Xiu focused his gaze beyond the Bronze Giant Gate.

In the gap that just barely allowed a person to pass through was a swirling gray mist, seemingly devoid of anything inside, just an empty space.

"Such dense Yin Qi," Jiang Miaoyin remarked.

Chu Xiu nodded.

He had previously felt something was strange, as the Exorcist Civilization manipulated ghosts to fight, and exorcists among them required Yin Qi cultivation, with the city’s operation centered on Yin Qi as its energy core.

Regardless, they should have chosen to situate their city in a place dense with Yin Qi.

But the city just outside, had only slightly more Yin Qi than other places, completely unable to satisfy the cultivation needs of exorcists.

At first, he thought the array that gathered Yin Qi had been damaged over the long years, but now it seemed that some entity had gathered all the city’s Yin Qi here.

"Such rich Yin Qi could have given birth to extremely strong ghosts. Be careful, senior," Jiang Miaoyin warned.

Chu Xiu nodded, and suddenly, a surge of Demonic Qi erupted, surrounding him as he stepped forward.

He was not particularly afraid, rather he was somewhat expectant. If the ghosts nurtured by such dense Yin Qi over two thousand years could have their Soul Bodies absorbed, it would allow his Ghostly Legion to strengthen immensely!

Additionally, it was not impossible for a Legend to emerge.

"Plop."

As Chu Xiu stepped in, the dense Yin Qi around immediately recoiled violently as if meeting a nemesis.

Jiang Miaoyin followed closely behind him, and the two strolled into the fog.

Within this gray mist, their Divine Sense was greatly affected, with a coverage of only about five hundred meters. Even Jiang Miaoyin’s probing Curse Spirits seemed severely weakened, and she frowned continuously, cautiously looking around.

However, despite walking for a long time, all they saw was the dense gray mist, with no enemies, buildings, or anything, only the extremely dense Yin Qi continuously corroding their bodies.

Jiang Miaoyin shivered and even shuddered.

"Senior, something is amiss here."

Chu Xiu did not reply, only squinted his eyes, and a faint golden light arose in his pupils, seemingly able to penetrate all illusions and reach the depths of the fog.

Suddenly, as if activating some mechanism, the gray mist around them began to surge violently!

"Boom!"

A giant sound like the ringing of a great bell echoed in their ears, followed by a majestic voice: "How dare you trespass on the Holy Altar!"

As the voice fell, the gray mist quickly dissipated, and in their shocked gazes, the surrounding world seemed to suddenly gain color: dim yellow lights appeared out of nowhere, pillars engraved with ancient giant beasts rose from the ground, and stones paved the ground before them.

Furthermore, there were flowerbeds, fountains, the Exorcist Civilization’s unique Yin Sha Cannons, five-meter-tall soldiers in heavy armor, and enormous ghosts a hundred meters long floating in the air.

In just a breath’s time, everything around them underwent earthshaking changes, as if they had traveled back two thousand years to the peak of the Exorcist Civilization!

In front of Chu Xiu and Jiang Miaoyin stood a tall throne, and an oddly-featured humanoid creature sat above, with deep-set eyes staring at them with thick malice.

Chu Xiu sensed Jiang Miaoyin beside him suddenly freeze, her eyes shockingly filled with an expression of fear!

"This, this is a Domain!"

"But how could a King Tier ghost have developed a Domain!"

Domain?

The term made Chu Xiu pause, but before he could think further, the figure on the throne spoke again with a voice full of killing intent: "Those who dare to trespass on the Holy Altar will be executed without mercy!"

As the words fell, Chu Xiu suddenly found that, unknown to him, both the soldiers around and ghosts above, as well as the Yin Sha Cannons positioned around, were already aiming at him!

This caused him great alarm, a deeply strange feeling arising in him. He clearly remembered just a moment ago, these things seemed oblivious to his presence, doing their own things, yet now he felt those Yin Sha Cannons had been aimed at him all along, not just turned at the last moment!

Before he could figure out why, an ear-splitting roar sounded in his ears, and a massive white mist shot out from a Yin Sha Cannon, billowing towards him!

"Hmph."

Chu Xiu snorted coldly, and his Demonic Qi formed a large hand, swatting upward to disperse the condensed Yin Qi, yet much of the Demonic Qi froze upon contact with the white mist, as if ice crystals formed on the large hand.

Simultaneously, both soldiers and ghosts lunged at him. Chu Xiu’s expression remained unchanged, and he waved a Soul Banner, releasing a mass of ghosts to engage with his attackers, while he focused on the figure on the throne, pointing a finger.

In a flash, a green Spiritual Light shot forward, striking the figure’s chest!

The principle of capturing the leader first, he understood well.

Yet in the next moment, a strange scene occurred. The figure hit by the Soul Slaying Demon Finger did not dissolve as a Murder Ghost would, with flesh and blood melting away. Instead, with a surge of mist, even the chest wound disappeared.

Even more terrifying, each guardian and ghost killed by the Ghostly Legion would simultaneously resurrect in their original positions, unscathed! Even the Yin Sha Cannons that had fired would reload instantly within a second, as if time had reversed!

But this was neither time reversal nor illusion, as Chu Xiu could clearly feel that whether shell or guardian, the damage they inflicted was real!

These attacks were no mere annoyance but rather capable of instantly shredding a King Tier with a coordinated assault! The nearby hundred or so guardians, each one at General Tier with unique Divine Techniques, seemed like living individuals.

Overhead, the swirling ghosts included formidable King Tiers, and the Yin Sha Cannons nearby, the Exorcist Civilization’s core technology, were no less destructive than the modern world’s most powerful howitzers!

Under such a fierce assault, even Chu Xiu’s Ghostly Legion began sustaining damage!

This caused Chu Xiu’s expression to darken suddenly. He raised his hand, retrieving all his ghosts, while the Imperial Five Dragon Crown atop his head lit up, and five roaring Giant Dragons appeared above!

As the five dragons appeared, a scorching Celestial Fire swept outward, incinerating all enemies, while the five dragons intertwined, sharing mana and mutually promoting and sustaining each other, with an endless stream of Celestial Fire raining down, continuously burning the endlessly resurrecting enemies!

Chu Xiu unhesitatingly unleashed the full power of the dragons to let them fight autonomously!

No way he would allow his hard-earned Ghostly Legion to be consumed just like that.

Taking advantage of the interval where the five dragons held the enemy at bay, he turned to Jiang Miaoyin and quickly asked, "What exactly is a Domain?"

Jiang Miaoyin paused, surprised: "Senior, you don’t know?"

But she knew time was of the essence, quickly explaining to Chu Xiu.

"A Domain is typically a power only Gods can possess! Within a Domain, a God is omniscient and omnipotent, able to create or destroy anything at will!"

"Even if someone hasn’t ascended to godhood, they can wield the power of a Domain, but at the very least, it requires being a Demigod to touch or grasp such techniques!"

Upon hearing this, Chu Xiu’s expression turned grim: "You’re saying that the ghosts here possess powers that even Demigods might only have?"

"Not really," Jiang Miaoyin shook her head, "Soul Type entities, like Spirit Bodies without physical limits, are somewhat special, making it relatively easier for them to develop high-tier power utilization techniques. Many Heroic Spirit ghosts can open their own Domains."

"Moreover, this is a fixed Domain, a Domain that cannot be left."

"Even so, it’s incredibly rare for this to appear with a King Tier ghost! It’s manifesting the most glorious moment of the Exorcist Civilization here!"

"So that means..."

Jiang Miaoyin’s expression grew unprecedentedly serious: "We might have to face the entire Exorcist Civilization here as our enemy."
